Make it a fun game or competition to enhance student interest.
Ask students to find as many of the listed words as they can in the time period that you set. When the time is up, ask students to add up all their points to see who got the most.
If you have honors or advance level students, you can hide the word list when photocopying to make it more challenging for them.

Many more biology puzzles will be added soon. Please *FOLLOW ME* to be notified when another word search puzzle is added to my TpT Store. Thanks!
